Abstract (en)
A turbine assembly (100), in particular a gas turbine stator assembly, includes a second component (104) circumferentially adjacent to a first component (102), wherein the first and second components, in particular shroud or nozzle segments, each have a surface proximate a hot gas path and a first side surface of the first component to be joined to a second side surface of the second component. The assembly (100) also includes a first slot (128) formed longitudinally in the first component which extends from a first slot inner wall to the first side surface (120) and a second slot formed longitudinally in the second component which extends from a second slot inner wall to the second side surface (120). The first and second slots are configured to receive a sealing member. The assembly (100) also includes a first groove formed in a hot side surface of the first slot, the first groove extending from the first slot inner wall to the first side surface (120), wherein the first groove comprises a tapered cross-sectional geometry.
